Business Footprint Calculators
• Canadian National Railway Company
This footprint calculator generates carbon-emission estimates for shipments using a combination of vessel, rail and truck-such as containers moving internationally from Asia to North American destinations along CN’s network-or domestic shipments using a combination of rail and truck or a single mode of transportation.
• Climate Action Registry Reporting Online Tool (calculation and reporting tool)
The greenhouse gas emissions calculation and reporting tool serves as a companion to the California Climate Action Registry’s general reporting and certification protocols.
• Energy Department’s Transparent Cost Database
This public database provides cost and performance estimates for renewable electrcity generation, advanced vehicles, and biofuel technologies.
• EPA Greenhouse Gas Equivalencies Calculator
This calculator helps users, for example, understand what reducing carbon dioxide emissions by metric tons means in everyday terms. For example, if five gallons of gasoline is entered as not being burned, the calculator determines it is equivalent to removing 0.04 metric tons of carbon dioxide from the atmosphere.
• ERM’s Carbon Calculator
The consulting firm ERM developed a carbon calculator to provide a basis for assessing an organization’s overall footprint.

• PaperCalculator.org (Environmental Defense Fund)
This tool helps quantify the benefits of paper choices by showing the environmental impacts of different papers across their full life cycle.
• PAS 2050
Sponsored by the United Kingdom’s Department for Environment, Food, and Rural Affairs (Defra) and the Carbon Trust, Publicly Available Specification (PAS) 2050 was designed to provide consistent method for assessing the life cycle GHG emissions of goods and services.
• Xerox Sustainability Calculator
This calculator provides a side-by-side comparison of a various types of printers by generating estimates of their environmental impact. Results are provided for a printer’s energy consumption for its life cycle, greenhouse gases emitted, and sold waste generated.
